I recently got a brand new pair of Isport Immersion headphones for $40 opebox at a local store. Now I am not a Monster fan, I like my Etymotic HF3, but I thought it was a decent deal so I got them. The problem is that whlie they sound decent, and I spent well ver an hour trying different tips\ear loops, they really do not block out that much outside sound. What other tips could I try to remedy this? I can take these back if they do not work out, but would like to see if I can make them work. Edit: I took them back, found them too annoying and bulky.
